Circa 1937-1951: Marked in the mold on the bottom. Unlike the large teapots where many pieces had to be attatched by hand, the medium sized version came with a one part mold for the lid, resulting in a straight knob and perfect proportions every time. This vintage fiesta teapot in the original Green glaze is an excellent example, in fantastic condition with great glaze and rich, even color. They don't come any cleaner than this piece. Marked in the mold on the base "HLC fiesta MADE IN U.S.A." Measures 8 1/2" w x 5 1/8"h.
